MiniMax H3 video model runs OOM-free on 16GB VRAM via temporal window + spatial tiling
Select_Bowler3099 · reddit · 2026-11-07
A r/StableDiffusion user reports that the ComfyUI plugin ComfyUI-MiniMaxH3-TemporalWindow-SpatialTiles lets the MiniMax H3 video model run on a consumer setup with just 16GB VRAM and 32GB RAM without OOM, using temporal windowing and spatial tiling as memory optimizations. Useful reference for local video generation on low-VRAM GPUs.
